RESUMO
Processing of inactive pro-sigma K to active sigma K in the mother cell compartment of sporulating Bacillus subtilis is governed by a signal transduction pathway emanating from the forespore and involving SpoIVFB in the mother cell. Coexpression of spoIVFB and sigK (encoding pro-sigma K) genes in growing B. subtilis or Escherichia coli enhanced pro-sigma K processing in the absence of other sporulation-specific gene products. The simplest explanation of these results is that SpoIVFB is a protease that processes pro-sigma K.
